[QUOTE="Horoscope Fish, post: 618612, member: 13090"] As I look at things the camera's exposure meter is there to give me [I]consistent[/I] exposure, based on a Standard (of reflective light). 18% is what we used for a long time, thanks to Kodak, but what the exact nature of the Standard is, precisely, is really inconsequential since only the photographer can determine what is "proper" exposure for a particular shot. That being said, this is how the different metering modes work... [COLOR="#FFFFFF"]....[/COLOR] [B]Center-Weighted[/B] metering biases the meter to a central portion of the frame, regardless of focus point(s) employed. Just how large an area that central portion of the frame used to determine exposure IS can be adjusted to a degree but a constant with Center-Weighted is that it is always the center of the frame that is biased at 75% in calculating exposure, with the remaining bits of the frame comprising the remaining 25%. This is how Nikon explains it: [COLOR="#FFFFFF"]....[/COLOR] [B]Spot[/B] metering biases the exposure calculation to that very specific portion of the frame that falls under the focus-point, wherever that focus point happens to be in the frame. Put the focus-point on what it is in the frame you want exposed properly (as based on the Standard) and you're good to go. There's nothing particularly exotic about it, you simply need to understand how it works and it's not exactly rocket-science. In my mind I ask myself, "What, [I]exactly, and too the exclusion of everything else in the frame,[/i] do I want to be "properly" exposed?" That's where I put the "spot" when using Spot metering.
